Working principle of front gate valve

Front gate valve is a type of valve used in tap water network management, which is equipped with a locking device to prevent non operators from opening or closing it on their own. Its working principle is relatively simple, and the following is its basic working principle:

1. Structural composition: Front gate valves are usually composed of valve body, valve cover, gate plate, valve stem triangle lock, and other parts. The gate is the core component of a valve, used to open or close the passage of fluid.

2. Fluid flow: The design of the gate valve in front of the meter reduces the flow resistance of the fluid when passing through the valve, so it hardly affects the flow of the fluid in the open state.

3. Sealing: When the valve is closed, the sealing design between the gate and the valve seat ensures that the fluid does not leak, maintaining the safety and effectiveness of the system.

The switch type of the front valve adopts a triangular lock head, which can be opened or closed with a special wrench to prevent the use of ordinary switches. The protective structure is dustproof and waterproof, and prevents other tools from impacting, effectively protecting the losses of the water company or other users. The structure is simple and easy to operate.
